  • Method and structures for indexing dice
    Patent number: 7868474
    Abstract: A method of indexing a plurality of dice obtained from a material wafer comprising a plurality of stacked material layers, each die being obtained in a respective die position in the wafer, the method including providing a visible index on each die indicative of the respective die position, wherein providing the visible index on each die includes: forming in a first material layer of the die a reference structure adapted to defining a mapping of the wafer; and forming in a second material layer of the die a marker associated with the reference structure, a position of the marker with respect to the reference structure being adapted to provide an indication of the die position in the wafer.
    Type: Grant
    Filed: February 10, 2009
    Date of Patent: January 11, 2011
    Assignee: STMicroelectronics, S.r.l.
